To all whom it may animera.'

Be it known that I, RUDOLF (inlener, a Subject. of theEmperor ofGermany, and resident of Berlin, Germany, have invented certainfnew anduseful Improvements in Methods ot Heating` (ol e-( )\'ens, of -which`the following in a specification.

In' United States Letters lalent 1,208,134 issued to applicant December1.9.16,iipplicant lrasdesrrihed an invention mul-#nataleoorieration ott-olce ovens with elosedretorts externallyY healed and which refersparticolari)7 to a process of heating eokeoven's with either producergas or il'lun'iinating gas' such ae is ohtaiueil for instance', in theeoking oi coal. a partieular feature 0i' thinI inmress being thegeneration of a linited quantity ol prmlucer gan dun4 ing the period oflun-ning; illuminating ,iran in order to keep the i'uel hed of the gasproducer hot enough lo permit. ou a -uiolaents noline; the heatingr otthe eoliing oven exelusii'ely by producer gan instead ot' byil'llunirnitinzgr rgras.

In the present aliplication isrdesoribed a further improvement. on thisprot-ess by i which considerable advantages are effected with `thequantities of vprodl'Lt-er gas gener ated, in the manner describedbelow.

According to the present-l invention the gas' used in therheating of,the

The hot useousproducts resulting ,from the com ustioniof the illuminatingr gas.chiefly ear-- bon `dioitidl gas and water vapor. travel through ythegenerator and keep its fuel bed in an incandescent state, being,-however, at the same `time transformed into carbon monoxid and hydrogengas, which latter are conducted into the furnace' proper to he burnedthere for heating the retorts. v "The present invention affords thegreat convenience that only small quantities of solid fuel are to beburned by air in the Specication of Letters Patent.

The procese will he. fully understood by referringr lo the.accoinpanying draiying'- which illustrates in a vertical section one wayot' eomtructing both a Coking-oven and a .nan producer suitable for theoperation of the irn'ention. v

The gas'produt-er r/ ie eonnet'ted by a crossrhannel b and lateralehanncln t', branching oli' from cross-channel fr, with the furnacerhaniher in which the retorts rf are located. The air for theiconibustion `of the gas is admitted byaneaus ofthe channels f openinginto the upper part of the lateral channels (n In order to regulate thevolume ot' air neoessary for the producticiniof produeergas a. platevalre g isprovidcd in the lower door h of the gan producer. 4Alna pipe Efor illuminating' gas, `provided n" .shut otfvalves la, is connected tohorizontal channels vii leadi'rng ,through the wall of the generatorWhereA their exits n are in juxtaposition to the exits p of channelsl r]regu! lated hy plates r and serving for the-adV mission of air.

While the oven is being heated produrer gas the valve ld of the-)naingas ipe/i and the plates Ir of the channels (l are c used,

whereas the plate admitting and regulat- /ing the'entraiue of'air totheproducer, is

rather wide open so that all the producer gus necessary for operatingthe eoking oven Vmuy he generated.

During the period of burning illuminating gas the plate g ,isa openedonly very little. i'f opened at all,;so` that at this pointionly verylittle air, or none respectively muy enter.

The process described in the resent appli-' cation is like theprocessdescri' ed in United lStates Letters Patent No. 1,208,134 issued toapplicant December 12,1916, suitable not only in case frequent lchangesin theI manner of heating the coking ovens have to be resorted to, butalso offers great advantages 1n case the same are to be `heatel'viit-hillueontinuously, because rendering the gas non-Y lunnnous is thenalways desirable and often y becomes a direct necessity. Also in theVcases where no particular is laid upon the application of non-luminousgases just-'as Well as in cases Where non-luminous gases are used forheating the coking oven, a most desirable and important advantage is ob*tained inasmuch as because of the hot fuel bed the producer explosionsare avoided and a remarkably great safetyin the operation of the processis obtained.

' The illuminating gas coming 'in consideration 'for the presentinvention is for instance derived from bituminous coal, lignite, peatand the like substances. The gas could also be freed from its luminousparts by being Washed with oils or other suitable like sub` stances. i

As inthe process disclosed in said Patent No. .1,208,134 which may becarried out in plants where the gas-producers and cok` ing ovens areseparated from each other by considerable distances7 so the process de#scribed in the present application may .be

' carried out in coking ovens which do not adjoin the gas producer, butwhere, for in stance, a large central station of gas producers isestablished somewhat remote from the. -coking ovens proper.
